Thanks for playing! Yeah I realized a little to late that the total day reset on death thing was a bit too much, I'm not fully sure what to do yet but I think for starters saving your stats at the point of changing from day-to-noon and so forth would be a good start.
As for the hitboxes on the jumping enemies they actually disable until they're just about to hit the ground, to make it like they're landing on you, but making disabling them when they're just standing still's a good idea, so I'll take that into account in the future.
I was going to add being hidden from enemies in the leaf pile but the deadline came a bit too close for me to add that, definitely plan to change that in the future, they do have another use in the form of replenishing ammo for one of the other weapons.
Lastly for getting other weapons, you do have to beat the level, where you'll be taken to a shop that'll let you buy weapons with the seeds you earn. If you hunt down the enemies optimally, you should have more than enough for the first extra weapon/just under enough for the first ranged weapon.
